22:24 <timsu> I want to compile my mainline Kernel 6.9 for Longan Pi. First I run `make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu sunxi_defconfig` which creates my .config file. After that I run `make`. Why does it say "Restart config" and I have to select lots of options. Shouldn't this be preconfigured?

22:28 <gnarface> timsu: not sure why, but did you forget to pass ARCH and CROSS_COMPILE to the second make?

22:32 <apritzel___> timsu: you have to give ARCH= and CROSS_COMPILE= for each call of make

22:32 <apritzel___> best is just to export them in your current shell

22:32 <apritzel___> and also: it's ARCH=arm64

22:33 <apritzel___> and there is no sunxi_defconfig in arm64, so just use defconfig

22:34 <apritzel___> and expect to add quite some more options, especially if you want to compile them in

22:35 <timsu> okay, this works now. But should these default options be enough to get a basic booting kernel?

22:36 <apritzel___> basic booting: yes, that's the idea of the arm64 defconfig

22:36 <timsu> serial debug console should also work, right?

22:37 <apritzel___> yes, it includes all clocks, pinctrl, and MMC

22:37 <apritzel___> I suggest you use "console=ttyS0,115200n8 earlycon" on the command line

22:38 <apritzel___> the latter gives you early output, before the console driver has probed
